  • Requires Flatpak for installation (https://flatpak.org/setup/)
  • Mono is no longer required
  • The UI should now feel like a native Linux app
  • Much better performance and reliability

  • In some cases this means much faster import/export
  • Pdfium is bundled with the NAPS2 download so there is no longer an extra download needed to import non-NAPS2 PDFs
